Why Dauphin County homeowners request radon help

Radon can enter through cracks, sump pits, crawl spaces, gaps around pipes, and other openings in or below the foundation. Because it is invisible and odorless, homeowners should rely on test results rather than assumptions.

A provider serving Dauphin County can review your test result, foundation type, basement or crawl space layout, and any real estate deadline. The typical goal is to design a system that pulls radon from beneath the home and vents it outside.

You may want to request an estimate if

  • Your test came back at or above 4.0 pCi/L.
  • You are buying or selling a home and the inspection found elevated radon.
  • You plan to finish or regularly use a basement.
  • Your existing radon fan is noisy, failed, or not showing normal pressure.
  • You need help understanding whether testing, mitigation, or fan replacement is the right next step.

What to include in your request

When requesting a quote, include your ZIP code, test result, whether the home has a basement or crawl space, and whether there is a settlement deadline. If you have a copy of the inspection report, keep it nearby for the provider conversation.

Before hiring, confirm that the provider is currently certified for radon mitigation in Pennsylvania. PA DEP maintains a Radon Services Directory for certified radon testing, mitigation, and laboratory services.

Common questions

Do radon levels vary by neighborhood?

Yes. Radon can vary from house to house, even on the same street. The only way to know a specific home’s level is to test.

Should I wait if I am not selling the home?

A real estate deadline may create urgency, but homeowners can still request guidance when a test result is elevated or a lower-level living space is used regularly.

How do I verify a provider?

Use the PA DEP services directory to confirm current certification before hiring.
